How To Drain Dishwasher

Dishwashers are a lifesaver when it comes to cleaning dishes quickly and efficiently. However, sometimes you may notice that your dishwasher is not draining properly. This can be a frustrating experience, but don’t worry. In this article, we will guide you on how to drain dishwasher.

Why is my Dishwasher Not Draining?

Before we begin with the draining process, it’s essential to understand why your dishwasher is not draining. There can be several reasons behind this. Sometimes, the drain hose might be clogged, or the garbage disposal might not be draining correctly. In other cases, the dishwasher’s drain pump might be faulty, or the dishwasher’s filter might be dirty.

How to Check for Clogged Drain Hose?

The first step in draining the dishwasher is to check if the drain hose is clogged. To do this, turn off the dishwasher and disconnect the drain hose from the garbage disposal. Next, hold the drain hose over a bucket and turn on the dishwasher. If there is no water coming out of the drain hose, it means that it’s clogged. To unclog it, you can use a plumbing snake or a wire hanger and carefully insert it into the drain hose to remove the blockage.

How to Check for Faulty Garbage Disposal?

If the drain hose is not clogged, the next step is to check the garbage disposal. Sometimes, the garbage disposal might not be draining correctly, which can affect the dishwasher’s draining process. To check for this, turn on the garbage disposal and listen for any unusual noises. If it’s not working correctly, you might need to call a plumber to fix it.

How to Clean the Dishwasher Filter?

Another reason for the dishwasher not draining could be a dirty filter. To clean it, you need to remove the bottom rack of the dishwasher and locate the filter. Carefully remove it and clean it under running water. Once cleaned, place it back into the dishwasher and run a cycle to check if it’s draining correctly.

How to Check for Faulty Drain Pump?

If none of the above methods work, then the issue might be with the dishwasher’s drain pump. To check for this, you need to locate the drain pump, which is usually located at the bottom of the dishwasher. Disconnect it from the dishwasher and check if there are any blockages or damage. If you notice any damage, you might need to replace the drain pump.

How to Replace the Drain Pump?

If you need to replace the drain pump, make sure to turn off the power supply to the dishwasher before starting the process. Next, remove the old drain pump and install the new one. Once done, reconnect the drain pump to the dishwasher and turn on the power supply. Run a cycle to check if the dishwasher is draining correctly.
